A WordPress plugin is one you will find inseparable from this platform. If you are wondering and want to learn what is WordPress plugin this article will be your good starting point.

What Is A WordPress Plugin And How Does It Work?

Let’s start simple, a WordPress plugin is something that adds new functionality to your WordPress site or extends existing functionality. Imagine a bit of code that “plugs in” to your self-hosted website. Plugins are an essential building block of every single WordPress site.

WordPress plugins are written in the PHP programming language and integrate smoothly with WordPress. The WordPress community is saying: “there’s a plugin for that”. They make it easier for users without knowing a single line of code, to add features to their website. Developers, including ours at Webpigment, have written tens of thousands of WordPress plugins that you can add to your site.

For example, plugins can turn your website into a fully functioning eCommerce store, into forums, social networks, or add smaller features like Twitter feet. Also, there are plugins that don’t have front-facing effects, you can install them to improve your site’s performance.

So let’s go ahead and look at the default plugins that come with WordPress installations. From your WordPress dashboard to get to your plugins, you can come over in the left-hand navigation down to plugins, and this will take you to a list of plugins that are currently installed on your site.

If you want to add new functionality, you can come up to ADD NEW and it will take you to the WordPress plugin directory. Almost everything you can imagine to add to your WordPress site, there is probably a plugin that will do it.

You will notice that there are tons of free plugins and there are also premium or ones as well.

What Are Free Plugins?

Thanks to the WordPress developer community, there are literally 55,000 free WordPress plugins available for download. Аs we mentioned, the largest source of plugins can be found in the official WordPress Plugin Directory, but there are also third-party WordPress designers and developers who offer them.

Choosing the right WordPress plugin for your website is not easy – especially when you have thousands of free options out there. However, not all of them can be trusted, so remember to look out for:

  • Average user ratings
  • Active installations
  • User reviews
  • Support and documentation
  • Updates and compatibility

What are premium plugins?

Premium plugins are paid version of WordPress plugins that come with additional features, priority support, regular updates, and documentation.

  • Do you have to pay for WordPress plugins?

How WordPress Plugins Work

WordPress is written in a way so that other developers can contribute and add their own code to it. The WordPress plugin API provides a robust set of hooks and filters which allow developers to modify existing WordPress components or add new functionality. The developers can store data in the WordPress database. Plugins can utilize WordPress content types, taxonomies, and custom fields which allow users to store different types of content, not just posts, and pages. Each WordPress plugin that you install is recorded in your WordPress database. You can activate and deactivate them at any time you want.
